Introduction

Halloween Swamp Eggs are a spooky twist on classic deviled eggs, featuring a crackled blueberry-dyed shell and a vibrant green filling. Perfect for a festive party, they bring a fun and eerie touch to your appetizer table.

The image shows several cracked blue eggs with dark purple vein-like patterns on their shells. Some of these eggs are whole, while others are cut in half, revealing a creamy white interior with the same dark purple crack pattern. The halved eggs are topped with a swirl of bright green filling, which is textured like a soft mousse or whipped cream, and sprinkled with small black seeds in the center. All the eggs are arranged on a dark, textured surface, alongside a single dry brown leaf. The contrast between the bright green filling, the dark purple cracks, and the blue eggshells creates a striking visual. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

12 large eggs
1 1/2 cups frozen blueberries, thawed
1 1/2 cups hot water
3 tablespoons distilled white vinegar
12 large egg yolks (from the hard-boiled eggs)
9 tablespoons mayonnaise
2 tablespoons liquid chlorophyll
1/4 teaspoon salt
1/4 teaspoon black pepper
3 tablespoons minced fresh dill
2 tablespoons minced fresh chives
1 large clove garlic, crushed
1/2 tablespoon poppy seeds (for garnish)

Instructions

Step 1: Place the eggs in a saucepan and cover with cold water by about 3 inches. Bring to a rolling boil, then reduce to a slow boil and cook for 9 minutes 30 seconds.
Step 2: Transfer the eggs to an ice bath for 10 minutes. Once cooled, gently tap the shells all over to create fine cracks, but keep the shells on.
Step 3: In a blender, combine the thawed blueberries, hot water, and distilled white vinegar. Puree until smooth to make the dye mixture.
Step 4: Place the cracked eggs and blueberry dye into a gallon-sized zip-top bag. Remove excess air, seal the bag, and refrigerate for 24 hours, rotating the bag occasionally to evenly dye the eggs.
Step 5: After 24 hours, remove the eggs and place them on a wire rack. Let them air dry in the refrigerator for about 1 hour.
Step 6: Carefully peel the dried eggs to reveal the crackled pattern. Cut each egg in half lengthwise. Transfer the yolks to a large bowl and mash them well.
Step 7: Add mayonnaise, liquid chlorophyll, salt, and black pepper to the mashed yolks. Stir until smooth and creamy.
Step 8: Mix in the minced fresh dill, chives, and crushed garlic until evenly combined.
Step 9: Spoon or pipe the green yolk mixture back into the egg white halves. Sprinkle with poppy seeds for garnish and serve immediately.

Tips & Variations

Use liquid chlorophyll for a natural green color, or substitute with a few drops of green food coloring if preferred.
For a milder garlic flavor, reduce the amount of crushed garlic or omit it entirely.
To enhance the blueberry flavor in the dye, strain the puree before use for a smoother finish on the eggs.

Storage

Store the assembled swamp eggs in an airtight container in the refrigerator for up to 2 days. For best texture and flavor, serve them chilled but consume within this time frame. If you want to prepare them in advance, keep the eggs peeled and dyed separate from the filling and assemble shortly before serving.

How to Serve

The image shows several blue eggs with dark purple crack patterns on the shell, some whole and some cut in half. The halved eggs reveal a smooth white inner layer with the same crack pattern visible around the edges. On top of this white base, there is a swirl of bright green creamy filling, topped with small black round seeds as garnish. These eggs are placed on a dark textured surface next to a brown dried leaf, creating a rustic feel. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use fresh blueberries instead of frozen?

Yes, fresh blueberries can be used in place of frozen. Simply puree them with hot water and vinegar to make the dye as directed.

What if I don’t have liquid chlorophyll?

If liquid chlorophyll isn’t available, you can substitute with green food coloring or finely chopped fresh spinach blended into the yolk mixture for a similar color effect.

Ingredients

Scale

Eggs and Dye

12 large eggs
1 1/2 cups frozen blueberries, thawed
1 1/2 cups hot water
3 tablespoons distilled white vinegar

Filling

12 large egg yolks (from the hard-boiled eggs)
9 tablespoons mayonnaise
2 tablespoons liquid chlorophyll
1/4 teaspoon salt
1/4 teaspoon black pepper
3 tablespoons minced fresh dill
2 tablespoons minced fresh chives
1 large clove garlic, crushed

Garnish

1/2 tablespoon poppy seeds

Instructions

Make the Crackled Eggs: Place the eggs in a saucepan and cover them with cold water, ensuring the water is about 3 inches above the eggs. Bring to a rolling boil over high heat, then reduce to a gentle boil and cook for 9 minutes and 30 seconds.
Ice Bath and Crack Shells: Transfer the eggs to an ice bath and let them cool for 10 minutes. Once cooled, gently tap the eggshells all over to create a fine network of cracks without removing the shells.
Dye the Eggs: In a blender, combine the thawed blueberries, hot water, and distilled white vinegar and blend until smooth to prepare the natural blueberry dye.
Marinate Eggs in Dye: Place the cracked eggs into a gallon-sized zip-top bag. Pour the blueberry mixture over the eggs, squeeze out excess air, seal the bag, and refrigerate for 24 hours. Rotate the bag occasionally to ensure even coloring.
Dry the Dyed Eggs: After 24 hours, transfer the eggs to a wire rack and let them air dry in the refrigerator for 1 hour, allowing the color to set and the shells to dry.
Prepare the Filling: Carefully peel the eggs to reveal the crackled, dyed surface. Slice each egg in half lengthwise and remove the yolks into a large bowl. Mash the yolks until smooth.
Mix Filling Ingredients: Add mayonnaise, liquid chlorophyll, salt, and black pepper to the mashed yolks. Mix thoroughly to create a creamy and smooth green filling. Stir in the minced fresh dill, chives, and crushed garlic until fully combined.
Assemble the Swamp Eggs: Spoon or pipe the green yolk mixture back into the hollowed egg white halves, filling them generously.
Garnish and Serve: Sprinkle the filled eggs with poppy seeds for texture and contrast. Serve chilled as a festive Halloween appetizer.

Notes

Use fresh eggs for boiling and allowing proper peeling.
Handle eggs carefully to avoid breaking the cracked shells before dyeing.
Liquid chlorophyll enhances the green color naturally but can be omitted if unavailable; you may add a small amount of green food coloring as a substitute.
For a stronger blueberry flavor, use fresh blueberries if possible.
Marinate eggs longer for deeper color; up to 48 hours can intensify the effect but may darken the shell.
Chilling eggs after cooking improves peeling ease.
Make sure to remove air from the bag during dyeing for consistent coloring.
